When I added speakers of the same brand and model as I had been listening to for years, I believed I did hear a difference for the first very few moments. When I added a new pair of very close Family Resemblance mains, I believed I heard a similar variation in the sound; again, for a very short amount of time.
Was the main difference for simply tens of seconds? Yeah; could be
but there was a percieved change of sound that lasted for a noticable, though short, ammount of time.
This report is a good thing in my estimation, as it allows me(and others)to sit firmly on the fence in this matter and offend no one and agree with everyone!
The only problem that I face is the data. The data says there is no significant change, but the data collecting device at my house says there is. The fact remains that the sensors and data collecting and analyzing equipment in my home cannot be scientifically verified at this point of time.
